ATTO R N EY Patented Dec. 13, 1932 UNITED STATES PATENT OFFICE JOSEPH FRANCIS COBELLO, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- THIRD TO ALBERT H. FRIEDMAN, ONE-THIRD T0 NORMAN FRIEDMAN, AND ONE- THIRD T0 JOSEPH F. COBELLO, ALL OF PHILADELPHIA, PENNSYLVANIA APPLICATOR FOR COLLAPSIBLE RESERVOIRS Application filed November 21, 1929. Serial No. 408,801.

My invention relates to an applicator adapted to replace the cover closure of a collapsible reservoir. It is more particularly adapted for use with the conventional collapsible tube in which such materials as vanishing cream, cold cream, facial cream, shaving cream of the no-lather type, ointments for application to the skin, shoe polishes that come in ointment form, photographers paste, body deodorants, etc., are sold, but may be used with any ordinary collapsible reservoir containing plastic or fluid material which r lowing one may wish to apply to a surface.

It is necessary now to squeeze the material out of the tube, then on to a conveyor such as a piece of cloth, pad, the fingers, etc., and from the conveyor to the final surface. If the fingers are used as the conveyor a great inconvenience is produced because of soiling of the hands, and if a cloth or pad is used the necessity of having a conveyor that is hideous in appearance, that becomes lost or misplaced and requires a superfluous space when not in use also causes inconvenience. This is especially true in the case of toilet articles where even the appearance of uncleanliness must be avoided.

It is an object of this invention to provide an applicator which may be connected with a collapsible tube so that the material may be applied directly from the tube to a surface, and which will be unobjectionable from the standpoint of cleanliness and efficient operation.

lVith these ends in view my invention embodies an applicator, that possesses a soft massaging or rubbing surface and a valve to cut off the admission of fluid to the surface, and is adapted to be placed over the opening of an ordinary collapsible tube.

With these and other objects in View my invention consists in the following details of construction and combination of parts, as will be more fully understood from the folspecification and drawing, in which Figure 1 is a perspective view showing my improved applicator attached to an ordinary collapsible container:

Figure 2 is a plan view of the applicator:

Figure 3 is a sectional view taken on the line 33 of Figure 2: v

Figure 4 is a perspective view of my slide valve:

Figure 5 is a sectional view taken on the line 55 of Figure 2.

Referring to the drawing, in Figure 1 I have shown a conventional tube 10 of the type referred to and formed with an externally threaded nipple 12 adapted to receive an ordinary cap, and also the applicator in place of the usual cap. While the applicator, shown in greater detail in Figures 2 and 3, is shown as screwed on, this feature is not essential, as it may be fixed in place in any usual or desired manner.

My applicator comprises a body portion generally designated as A, a pliable pad generally designated as B and a slide valve generally designated as C.

The body portion A' comprises a horizontal circular base 14, provided with a central opening 16. From the lower side of the base an internally threaded neck 18 protrudes, the threads being designated by the reference character 20. A circular wall portion 22 projects vertically from the upper surface 24 of the circular base 14. The upper part of the wall, which functions as a retainer ring, projects radially inwardly, as designated at 26, a suflicient distance to retain the pad B in place and to permit the pad to extend thru its center. Openings 28 and 30 are provided in the wall portion 22 for permitting the slide valve C to pass thru, and the openings are so positioned that the slide valve rests on the upper surface 24 of the horizontal base 14.

The pliable pad, generally designated as B, may be of any resilient material, preferably rubber, and is formed with an opening or passageway 32. Project-ions 0r cor rugations 34, on the pad, provide means for massaging or spreading purposes or for ap plying fluid to properly designated surface. The pad B is constructed to be held within the wall 22, the inturned wall or retainer ring 26 and the base 14. The projections 34 extend thru the ring 26.

While it will be observed that the portion of the pad 34 is the spreading surface and that the surface is illustrated as being roughened, its character depends on the use of the material in the tube. A roughened or corrugated surface may be preferred when a massaging or cleaning action is desired, while a smooth surface may be preferred when no such action is desirable.

My slide valve, generally designated as C, is constructed of an elongated bar 36, having downturned ends 38 and 40 that act as stops for the valve. An opening 42 is located to one side of the center of the bar 36 for permitting the passage of fluid. It will be noted that the pliable pad provides a resilient action on the valve to prevent its slipping and to retain the valve in place. The pad has a channel 44 in its lower surface (Fig. 5) to receive the valve, the channel being constructed of a depth slightly less than the depth of the slide valve in order to keep this valve under slight pressure. By having the valve keep a tight fit over the opening 16 evaporation of the fluid is prevented.

Whilethe wall 22 is shown as being externally screw threaded, as designated at 46, for the purpose of receiving an internally threaded cover 48 (Fig. 1), this feature is not essential since it may not be desirable to provide a cover.

The mode of operation is as follows :My applicator in its entirety is substituted for the original closure of the reservoir, the neck 18 screwing on the nipple of the reservoir. When it is desired to apply the fluid to any surface the slide valve is pushed to its open position, the openings 32, 42 and 16 coinciding, so that the fluid may then be forced out. The reservoir acts as a handle and may be oscillated or rotated depending on the service desired. When a sufiicient quantity of fluid has passed thru the openings the slide valve is pushed to its closed position, so that the slide valve opening 42 does not coincide with the openings 32 and 16.

en the contents of the reservoir are completely gone, my applicator may easily be detached and then attached to a new reservoir of the same type of contents.

Although the invention has been described in considerable detail, such description is in tended as illustrative. rather than limiting. as the invention may be variously embodied, and the scope of the invention is to be determined as claimed.
